Does anyone know a source for DIP clips with wires attached? I am
looking for a way to connect my programmer to a target chip, whithout
having to do solder work on a DIP clip.

Wouldn't it be better to use female wire-to-socket connectors?
So if the clip or wires get damaged, they can easily be repaired.
Can't say I know of a source for what you are looking for
specifically, but I do remember sometime back seeing a
clip that would attach to a DIP package with probes /
hardwire terminals coming out the top that would
allow you to attach scope / logic analyser probes to it.
Maybe you can search some scope / logic analyser supplier sites.
If you find them them, then with a little wire and solder you will have
what you are looking for.
Sorry that I could not be of more assistance.

You mean the female equivalent of flatcable DIP connectors? I have never
seen those, they would not do what I want: I want to attach to an chip
in a circuit. The chip might be soldered, so an 'in-between' is not
always possible.

You mean a DIP clip? That is what I am using right now (see attached
jpg), works OK but it is a bit flimsy. I would like to avoid the
soldering part and have something more robuust.

The usual test clips are available with connector-compatible pin headers
at the top, onto which you should be able to plug Molex "KK" series
female terminal housings with individual crimp wire contacts. Then you can
use nice AWG26 or AWG28 wires for long life with flexing etc.

You could connect a crimped 0.1 socket to the dip-clip instead of soldering
them. Something like RS stock no: 296-5022 for 10 way (molex stock no is 22
01 2105) . Crimping tool is needed, and their price varies a lot. If might
be able to get some of free ribbon-cable with IDC to fix-in.

There are dip clips with I tops to hook a scope cable to. You can solder
wires to them. I have two but there is nothing written on them. They used
to be very common during LSI/MSI logic days ?
There is the method of the stacked offset board. This works if your chip
is on a socket. Basically it's a 'pin protector' but there is a small
board between the female and male sockets and the flatcable is connected
to the board. Would this help ?

Only sometimes. As you imply it does not work when the chip is soldered.
